IMPROVEMENTv IN DREDGlNG-MACHINES.

Specification forming part of Letters Patent No. 130,213, dated August 6, 1,8712.

Specification describing a certain Improved Dredging-Machine, invented by HYAGINTHE GONELLAZ, of Houma, in the parish of Terre- A in the drawing represents part of the end of a vessel to which my improved dredging apparatus is applied. B is the frame erected thereon for the support of the dredging-wheel C and of the mechanism for moving the same. The axle a of the dredging-wheel is hung in pivoted arms b b, so that thereon the wheel may be lowered to greater or less depth. This is regulated by means of bolts or chains d d. The dredging-wheel consists of three, more or less, parallel series of alternate colters, e e, and buckets ff, each series being arranged in a separate circle. The colters are shaped somewhat like plowshares, and serve to cut and loosen the ground in advance of the buckets which take it up. Each bucket f contains a swinging back or dumping-spoon, g, which serves to empty the bucket of its contents when arrived in proper position. D is the rst receiving-pan, suspended by pivoted rods h h from the top of the frame B, which are connected by rods t' z' with'a crank, j, on the operatingshaft E of the mechanism.

Whenever a lled bucket arrives in front of the pan D the latter is swung toward thesame into position to receive the contents discharged therefrom.` The pan is then carried back and dumps its contents into a second distributingpan, receiving-reservoir, or tank. Whenever a bucket,f, arrives in front of the pan d, in position for discharging its contents, the spoon g in such bucket is vibrated by gravity and by its connection, or either, to insure a complete discharge.

Motion is imparted to the wheel C by means of a loose crank, m m,'on its axle a, engaging into ratchet-teeth l l that are formed in the ends of the wheel. The cranks m m are, beyond a, connected with cranks o on the driving-shaft E, and thereby receive their vibrating motion, whlch, on the wheel C, is converted into intermittent rotary.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The colters e, the buckets, f, the dumpingspoons g, and the pans l), all combined and arranged in a dredging-machine to operate as described.
